UK Oil & Gas Investments PLC Announces Significant Upgrade of Horse Hill Discovery
Apr 9 15
UK Oil & Gas Investments PLC announced that Nutech Ltd. estimated that the Horse Hill-1 (HH-1) well in the Weald Basin has a total oil in place (OIP) of 158 million barrels (MMBO) per square mile, excluding the previously reported Upper Portland Sandstone oil discovery. The Horse Hill licenses cover 55 square miles of the Weald Basin in southern England in which the company has a 20.36% interest. Nutech's report to the company states this OIP lies within a 653 feet aggregate net pay section, primarily within three argillaceous limestones and interbedded mudstones of the Kimmeridge, and the mudstones of the Oxford and Lias sections. Approximately 72% of OIP, or 114 MMBO, lies within the Upper Jurassic Kimmeridge interbedded limestone and mudstone sequence. In order to establish estimates of total OIP within the license area, the semi-regional resource potential of the Weald Basin's eastern footprint is the subject of ongoing analysis under the contracted alliance between Nutech, UKOG and Solo Oil Plc. Final assessments of the Upper Portland Sandstone and the Oxford and Lias sections are in progress.
UK Oil & Gas Investments plc Provides Update on Horse Hill Discovery
Mar 18 15
UK Oil & Gas Investments PLC announced that ongoing well analysis of the Horse Hill-1 well (HH-1) in the UK's Weald Basin with alliance partner NUTECH Ltd. (NUTECH) has identified that, in addition to the previously reported 102 feet of Portland sandstone gross oil pay, a further 407 net feet of potential oil pay calculated from electric logs exists within limestones and claystones of the Kimmeridge Clay (Kimmeridge), Oxford Clay (Oxford) and Middle Lias (Lias) Formations. Detailed geochemical analysis, comprising a total of 270 Total Organic Carbon (TOC) and 28 RockEval pyrolysis analyses, was undertaken on drill samples, predominantly at 10 foot depth intervals, from 2,510 to 5,530 feet measured depth (ftmd) and 6,680-8,620 ftmd covering the main formations of interest in the prospective Jurassic Portland, Kimmeridge, Oxford and Lias sections of the well. Furthermore, these geochemical analyses have been incorporated by NUTECH into a preliminary electric log interpretation of the HH-1 well which demonstrates that, in addition to the previously reported 102 feet of Portland sandstone gross oil pay, a further 407 feet of potential oil pay exists in the well within the limestone and claystone sections of the Kimmeridge, Oxford and Lias Formations. The results of the HH-1 detailed geochemical analysis confirm and conclude that the 1,496 ft vertical thickness of Kimmeridge section in HH-1 contains three discrete thermally mature, highly organic rich, world class, claystone source rock units lying directly above, below and between the Upper and Lower Kimmeridge micritic limestone bands. The Upper, Middle and Lower Kimmeridge source rock units contain in excess of 780 feet of drilled section exceeding 2% TOC by weight, with an average of 4.1% TOC. The richest section, and possible sweet spot, lies between the base of the Upper Limestone and Top Lower Limestone at 2,931-3,084 ftmd with an average of 5% TOC and a high of 9.4% TOC. Additional pyrolysis results confirm that the source richness of the three Kimmeridge source units is very high with measured Generative Potentials (S2) ranging from an average of 35 kg/tonne to a high of 103 kg/tonne and with Hydrogen Indices (HI) averaging 754 with a high exceeding 1,000. The new geochemical analyses demonstrate that an additional 140 feet thick, thermally mature, claystone source rock unit, exceeding 1% TOC, exists at the base of the Middle Jurassic Oxfordian to Cornbrash section from 5,400-5,540 ftmd. A distinct 50 foot section from 5,450-5,500 ftmd shows average metrics of 2.6% TOC, S2 of 16 Kg/tonne and an HI of 617. Furthermore a 60 foot thick section of the Lias from 7,400-7,460 ftmd exceeds 1% TOC, with average metrics of 1.5% TOC, S2 of 5 kg/tonne and HI of 443. More samples from this 60 foot Lias zone will be sent for additional RockEval pyrolysis. The three Kimmeridge source units with TOCs above 2%, are interpreted by NUTECH to contain a total of 334 feet of net oil saturated potential pay. This interpreted Kimmeridge pay section demonstrates an elevated resistivity response compared to background non-source units of similar lithology. An additional 43 feet of potential oil pay within a gross 90 foot interval is interpreted to exist within the claystones of the Middle Jurassic Oxford and Cornbrash section. A 30 foot potential pay zone in claystones is also calculated in the Lias, however, this interval has only two samples both demonstrating less than 2% TOC.
